Exercise Training Shows Glycemic Control Benefit
Regular exercise has long been appreciated as a way to prevent or treat
type 2 diabetes. Recent research shows exercise training can even help improve
glycemia in people who have had diabetes for many years and who are on insulin
therapy.
A group of researchers in the Netherlands assessed the impact of a 5-month
exercise training program on 11 male participants who had been living with
diabetes an average of 12 years. All were sedentary and were using insulin to
control glycemia. The exercise training program included resistance training
and a cardio workout of increasing intensity in three weekly sessions of 45
minutes.
After 5 months, during which the participants averaged 83% attendance,
testing showed they had less fat in the torso and more lean muscle in their
legs. They had improved glycemic control, with significant reductions in
fasting blood glucose levels and glycated hemoglobin (A1C)—from 7.6
± 0.3% to 7.2 ± 0.2%. The amount of insulin participants needed,
however, did not change.

Although the sample was small, based on the results the researchers
recommend an exercise training program be prescribed to all people with
long-standing diabetes.
